Mack Disc Brake Rotor

The Mack Disc Brake Rotor delivers the consistent, heavy-duty stopping performance required for modern Mack truck braking systems. Cast from premium-grade iron, this rotor pulls heat away from the friction surface to prevent the warping that often leads to steering wheel pulse. Its ventilated design uses internal cooling fins to keep airflow moving through the metal even during stop-and-go city driving. This temperature control is vital for protecting your brake pads from glazing, which keeps the pedal feeling firm every time you slow down. Since every unit is machined to exact tolerances, the Mack 21856634 maintains a hub-centric fit that keeps the wheel-end assembly balanced and free of vibration at highway speeds. This high-quality casting provides a dependable foundation for your entire braking system, helping you maintain shorter stopping distances over the long haul.
